Hello ACE,

I want to raise one issue for group comments that has come up in conjunction with fixing the IANA nits for draft-ietf-ace-oauth-authz:
In figure 16 we define mappings from OAuth Token introspection parameters to CBOR abbreviations. These parameters (should) correspond to the claims that could be found in e.g., a CWT.
CWT renamed one token claim, namely 'jti' (JWT ID) into 'cti' for CWT ID. However, this is not reflected in the registered Introspection parameters
(https://www.iana.org/assignments/oauth-parameters/oauth-parameters.xhtml#token-introspection-response) where only 'jti' is registered. This was overlooked when we originally defined the mappings in figure 16.

I would therefore put the following question to the group:

Does anyone object to this draft adding 'cti' as an OAuth introspection parameter?

The corresponding text would go into the list of additional parameters in section 5.9.2 and be something along the lines of:
"cti  OPTIONAL.  The CWT ID parameter has the same meaning and processing rules as the "jti" parameter defined in section 3.1.2. of [RFC 7662] except that the value is a byte string. "

Regards,

Ludwig
